GRAND-AM 101: The Rolex Series GT Class

June 21, 2012 | By GRAND-AM MEDIA

The GT, or Grand Touring, class has long been a staple of sports car racing, both in national and international competition. The cars are historically those production-based cars built from the street and modified for the race track, though some cars in international series have been built as specificbased race cars with production-lookalike bodies.

GRAND-AM has employed a two-class system for the Rolex Series since 2005, running Daytona Prototypes and GT cars.

GT cars competing in the Rolex Series can be unibodied production cars (Prep 1) or custom tube frame chassis (Prep 2). The rules for GT employ several methods of equalization, including race car weight, tire size and engine RPM limits to provide an even playing field for the variety of different cars. Engines in GT machines produce between 390 and 450 horsepower depending on the car.
